What I want to achive:I2S Audio Output on the included Arduino Header of the STM32F746G-Disco Board to drive a MAX98357A class-D amplifier.PB4 I2S2_WS on Ardunio D3 PI1 I2S2_CK on Ardunio D7PI3 I2S2_SD on Arduino D13To ensure that no configurable sol...
Hello forum,I'm (still) working on a data acquisition system based on STM32H743XIH6 MCU, I'm pushing the 16bit ADC to the limits and I'm stuck on a corner.Let me summarize first the actual code:1) TIM1 trigger every 1us ADC1 acquisition2) ADC1 acquir...
So, the situation has been pretty uncomfortable and frustrating.I'm trying to implement the code to make the USB-C on the STM32U5A9J-DK work so that my PC recognizes the board as a Device.I first started to try to implement it with my currently runni...
Hi there,I tried to add support for a PDM microphone, but so far I could only get 0's from DMA. Somehow, the polling method (HAL_SAI_Receive) did return non-zero values. Here is how I set up the SAI and DMA:I did so by modifying our project's existin...
Hi, I have created a program to send UDP using NetXDuo on a Nucleo-H755ZI.I used the URL below as a reference.Creating a dual IPv6 & IPv4 NetXDuo UDP application for STM32H7 using CubeMX I checked the operation in debug mode and could see that it is...
Hi,I am connecting ESP32 with STM32G474RET6 Nucleo board via SPI. I have configured SPI in DMA mode to transfer data. With NSS pin enabled for chip select I can see the pin remains low always during transmission of data and also in idle. So that I co...
My project is using a GPIO to enable/disable a buzzer on a software timer. This boils down to a call to HAL_GPIO_WritePin(), which does GPIOx->BSRR = pinmask (0x80 in this case) to enable the buzzer. This works as expected most of the time. There ar...
Hi team, I am working on stm32F7 discovery board, I am working on USB MSC Device however i am not getting , how to configure external flash of this discovery board as Mass Storage. My main goal here is as soon as i connect the controller t...
Hi, The SPI communication between an ESP(Master) and the STM(Slave) is failing when i configure the SPI clock at 10MHz.I have STM32F429ZIT6 DISC1 board and i have used SPI3 as slave, the SPI3 is on the APB1 bus which is configured at 45MHz PCLK.The c...
Hello!I just received some custom PCBs with the STM32H747BIT6 MCU, but I’m having trouble connecting to it. I’m using a J-Link V12 and initially tried to establish the connection with jlinkexe. It correctly detects the voltage, but when attempting t...
